I have the following problem. When I developed my application locally I was deploying it using Netbeans support. Now I need to deploy the application on the official server. I installed Tomcat6 and it displays the start page properly but how to deploy my app? Which changes are needed to make ot work on port 80 (at the moment it works on default 8080)? Where should I copy the files from my application? Thanks a lot for helping me out. Links to similar posts are also appreciated. I could not find any that would help me tough.
how to deploy my app
Netbeans on build operation creates a war file in dist folder. See a question about it here. You will need to take this war file and:
Where should I copy the files from my
application?
put it under webapp folder in tomcat.
The location is your tomcat_home folder->webapps.
Which changes are needed to make to
work on port 80
under your tomcat_home folder, open conf folder. Inside, find server.xml file. open it with notepad and change the port number from 8080 to 80:
<Connector port="8080" … />
should be:
<Connector port="80" … />
Don't forget to restart the server!
Now the link to your application will be:
http://localhost/YourWarFileName/
or the computer ip/name instead of localhost.

I followed a tutorial and am trying to learn to make my own web app. I am using Tomcat 8.0.47 and Spring MVC. Issue is I can go to localhost:8080 and see that the server is on but I cant see my basic webapp running when visiting localhost:8080/CrunchifySpringMVCTutorial page. I made a WAR file and dropped it into the /webapps/ folder inside tomcat folder and console shows that it deployed the war file. Any help is appreciated.
I am following this tutorial: http://crunchify.com/simplest-spring-mvc-hello-world-example-tutorial-spring-model-view-controller-tips/
rather than paste all the files I decided to link the guide. My set up is the same but cant figure out why it is not working. thanks.
Looks like the issue was that I needed to add the CATALINA_HOME system variable to properly setup my tomcat server
I am new to java web programming and eclipse-apache Tomcat. I have small login web-application which includes (one jsp page , one servlet class).
I want to configure/deploy this application on apache web application manager. I mean I don't want to run this application in eclipse. I hope you understand my point.
Whenever I run my server in eclipse it run successfully. But when I want to open apache default page by typing http://localhost:8080 or http://localhost:8080 to configure my app It wouldn't open.
Please advice me.
To deploy a web application on Tomcat, you need to first compile your web application into a WAR file. Then, take that WAR file (let's assume it's called "MyApp.WAR") and put that into the tomcat/webapps directory. Restart the tomcat service. Tomcat will extract that WAR to a folder in the webapps directory. After that, any request to localhost:8080/MyApp will go to your webapp.
Make sure you have java installed, and add JAVA_HOME to your environment variable. (it is the path to java installation directory for e.g. C:\Program Files\java\jdk-1.6)
i.e
JAVA_HOME=C:\Program Files\java\jdk-1.6
install TOMCAT from here "http://tomcat.apache.org/download-70.cgi"
make sure you do not install it in you "c:\program files" due to some permission issues.
Lets say you installed tomcat at "c:\webserver\apache-tomcat\" this is your CATALINA_HOME, add it to your environment variable
i.e CATALINA_HOME=c:\webserver\apache-tomcat\
to acess tomcat webapp manager you need to configure user in %CATALINA_HOME%\conf\tomcat-users.xml
Add a role and a user :
Have your WAR file ready with you (this is how you create WAR "How to make war file in Eclipse")
move your WAR file to "%CATALINA_HOME%\webapp" directory. lets say "TestWeb.WAR" is your application with index.jsp page in it.
Now go to your %CALALINA_HOME%\bin and launch the startup.bat file (you would be using startup.bat to start and shutdown.bat to stop tomcat)
once tomcat is up and running check http://localhost:8080 is working fine.
P.S. If port 80 is already in use then try configuring your tomcat to some other unused PORT here "http://www.mkyong.com/tomcat/how-to-change-tomcat-default-port/"
go to your browser type http://localhost:8080/TestWeb/index.jsp
now you can to lot of configuration to your web app like having a default page and all
Hope this help you !
Normally eclipse uses Tomcat as an eclipse project, hence it uses metadata.
Server > Double click on the tomcat server instance > Server Location > Select "Use Tomcat installation"
Update: Tested just now. Set Deploy path to webapps folder. Works fine :)
I have copied the sample.war file into the webapps directory of Tomcat, and I can access localhost:8080.
Now how will Tomcat deploy it, I mean do I need to open it in browser? How can I access the application?
You can access your application from: http://localhost:8080/sample
Deploying or redeploying of war files is automatic by default - after copying/overwriting the file sample.war, check your webapps folder for an extracted folder sample.
If it doesn't open properly, check the log files (e.g. tomcat/logs/catalina.out) for problems with deployment.
step-1. here I'm deploying pos.war First go to tomcat webapps folder and paste it
step-2. go to tomcat->bin folder start tomcat by clicking startup.bat
step-3. go to browser write localhost:port/project name eg. localhost:8080/pos (here my tomcat run on port 8080)
Done....
You just need to put your war file in webapps and then start your server.
it will get deployed.
otherwise you can also use tomcat manager a webfront to upload & deploy your war remotely.
Manual steps - Windows
Copy the .war file (E.g.: prj.war) to %CATALINA_HOME%\webapps ( E.g.: C:\tomcat\webapps )
Run %CATALINA_HOME%\bin\startup.bat
Your .war file will be extracted automatically to a folder that has the same name (without extension) (E.g.: prj)
Go to %CATALINA_HOME%\conf\server.xml and take the port for the HTTP protocol. <Connector port="8080" ... />. The default value is 8080.
Access the following URL:
[<protocol>://]localhost:<port>/folder/resourceName
(E.g.: localhost:8080/folder/resourceName)
Don't try to access the URL without the resourceName because it won't work if there is no file like index.html, or if there is no url pattern like "/" or "/*" in web.xml.
The available main paths are here: [<protocol>://]localhost:<port>/manager/html (E.g.: http://localhost:8080/manager/html) and they have true on the "Running" column.
Using the UI manager:
Go to [<protocol>://]localhost:<port>/manager/html/ (usually localhost:8080/manager/html/)
This is also achievable from [<protocol>://]localhost:<port> > Manager App)
If you get:
403 Access Denied
go to %CATALINA_HOME%\conf\tomcat-users.xml and check that you have enabled a line like this:
<user username="tomcat" password="tomcat" roles="tomcat,role1,manager-gui"/>
In the Deploy section, WAR file to deploy subsection, click on Browse....
Select the .war file (E.g.: prj.war) > click on Deploy.
In the Applications section, you can see the name of your project (E.g.: prj).
In addition to the ways already mentioned (dropping the war-file directly into the webapps-directory), if you have the Tomcat Manager -application installed, you can deploy war-files via browser too. To get to the manager, browse to the root of the server (in your case, localhost:8080), select "Tomcat Manager" (at this point, you need to know username and password for a Tomcat-user with "manager"-role, the users are defined in tomcat-users.xml in the conf-directory of the tomcat-installation). From the opening page, scroll downwards until you see the "Deploy"-part of the page, where you can click "browse" to select a WAR file to deploy from your local machine. After you've selected the file, click deploy. After a while the manager should inform you that the application has been deployed (and if everything went well, started).
Here's a longer how-to and other instructions from the Tomcat 7 documentation pages.
There are two ways:
Either you can do hot deployment (Hot deployment means deploying when server is running/up).
Or you can do cold deployment (Cold deployment means deploying when server is stopped).
Just use tomcat manager console for console deployment or simply copy and paste your application in webapp folder of your server's tomcat_home directory.
Note: Make sure if your war file size is more than 52 MB (the default configuration value),
you need to make two little changes in web.xml file of Manager application of your webapp folder(Manager application is provided by Apache tomcat by default upon installing the server).
Go to the web.xml of the manager application (for instance it could
be under /tomcat7/webapps/manager/WEB-INF/web.xml.
Increase the max-file-size and max-request-size values in web.xml file:
<multipart-config>
<!– 50MB max –>
<max-file-size>52428800</max-file-size>
<max-request-size>52428800</max-request-size>
<file-size-threshold>0</file-size-threshold>
</multipart-config>
Increase the size by putting the values for <max-file-size> and <max-request-size> according to your requirement.
This has been working for me:
Create your war file (mysite.war) locally.
Rename it locally to something besides .war, like mysite.www
With tomcat still running, upload mysite.www to webapps directory.
After it finishes uploading, delete the previous version mysite.war
List the directory, watching for the directory /mysite to disappear.
Rename mysite.www to be mysite.war
List the directory, watching for the new /mysite to be created.
If you try uploading the new file as a war file, with tomcat still running, it will attempt to expand it before it is all there. It will fail. Having failed, it will not try again. Thus, uploading a www file, then renaming it, allows the whole war file to be present before tomcat notices it.
Hint, don't forget to check that the war file's owner is tomcat (Use chown)
If you installed tomcat7 using apt-get in linux then, deploy your app to /var/lib/tomcat7/webapps/
eg.
sudo service tomcat7 stop
mvn clean package
sudo cp target/DestroyTheWorldWithPeace.war /var/lib/tomcat7/webapps/
#you might also want to make sure war file has permission (`777` not just `+x`)
sudo service tomcat7 start
Also, keep tailing the tomcat log so that you can verify that your app is actually making peace with tomcat.
tail -f /var/lib/tomcat7/logs/catalina.out
The deployed application should appear in http://172.16.35.155:8080/manager/html
For deploying the war file over tomcat,
Follow the below steps :
Stop the tomcat. powershell->services.msc->OK->Apache Tomcat 8.5->stop(on left hand side).
Put the .war file inside E:\Tomcat_Installation\webapps i.e. webapps folder i.e. put.war (put.war is just an example)
After starting the tomcat(to start tomcat powershell->services.msc->OK->Apache Tomcat
8.5->start )
you will get one folder inside E:\Tomcat_Installation\webapps**put**
In this way you can deploy your war file in Apache Tomcat.
1.Generate a war file from your application
2. open tomcat manager, go down the page
3. Click on browse to deploy the war.
4. choose your war file.
There you go!
The application name goes into the context of your tomcat deployed URL,
eg. http://localhost:Port/applicationName.
If your application name is simple then, it should be http://localhost:8080/sample.
By default, Port is 8080, but if you wish to change it, or want to know the port where tomcat is running, simply go to server.xml file in <tomcat-apache-dir>/conf/server.xml, there you can find port & change,
eg. <Connector port="8080" redirectPort="8443" connectionTimeout="20000" protocol="HTTP/1.1"/>
If anything goes wrong, check the log files (e.g. <tomcat-apache-dir>/logs/catalina.out)
Perform the following steps:
Stop the Tomcat
Right Click on Project and click on "Clean and Build"
Go to your project Directory and inside Dist Folder you will get war file that you copy on your tomcat
webApp Folder
Start the tomcat
automatic war file extract and run your project
I followed the instruction in the following link, it works for me.
http://www.coderanch.com/t/487178/Tomcat/war-file-show-load
Stop Tomcat
Delete all the logs in tomcat/logs and all files in tomcat/conf/Catalina/localhost
Remove the war file and the directory it created (if it did) from tomact/webapps
Start Tomcat
While watching the logs, copy the war file to the webapps directory again
After this, keep an eye on the catalina.xxxx-xx-xx.log to find out the issue.
I am able to get the spring blazeds examples and war (http://docs.spring.io/spring-flex/docs/1.5.2.RELEASE/reference/html/#pre-built-samples) working locally in tomcat 7 webapps directory (i initially had problems with this but now it works fine locally), however when I upload the same war file to amazon ec2, tomcats starts up fine and i can see the project's index page but none of the projects scripts are executing. According to the catalina.out log, the server started up successfully without any errors. Please help.
thanks,
tone
*Update
I am assuming that the problem resides in the blazeds portion of the project? Not sure if it is executing properly. i have enabled ports 8080 and 8400 in the security group.
Nevermind I found out the issue. i had to recompile the swf files that comes with the project to point to my ec2 instance url instead of localhost.
I have copied the sample.war file into the webapps directory of Tomcat, and I can access localhost:8080.
Now how will Tomcat deploy it, I mean do I need to open it in browser? How can I access the application?
